DEVICE FOR OPENING VIALS Filed March 8 192 Patented May 12, 1931 PATENT OFFICE WILHELM MERCK, OF DARMSTADT, GERMANY DEVICE FOR OPENING VIALS Application filed March 8, 1928, Serial No. 280,219, and in Germany March 18, 1927.

I 10 -With the above and other objects in view,

the invention consists in the construction, combination and arrangement of devices hereinafter described and claimed.

In the accompanyin drawings Figure 1 is a plan of a vial opening device constructed in accordance with this invention and with the parts thereof in one position.

Figure 2 is a similar view of the same showing the parts in another position.

Figure 3 is a similar view of the same showing the parts in another osition.

he vial opener is so ormed that it consists of a scissors-like part with lass cutter l and a circular striker 2 mounte on an arm 3, whereby the glass cutter takes up the position of the scissor blades and is best shaped circular, corresponding to the shape of the top of the vial. On the commencement of the operation of the opener the striker 2, on closing the hand grips 4 of the scissors, is pressed backwards by a disengaging lever 5, and when the cutting operation of the glass cutter is almost completed, is moved forwards, by slipping of the disen aging lever by means of a spring-actuated wire 6, against the cut top of the vial.

It is already known to open vials byvmeans of glass cutters. In this connection the glass cutter has either the shape of a pencil sharpener and the vial was inserted in the opening of this device and rotated about its own axis; or the vial o ener was shaped like scissors wherein the g ass cutter took the place of the scissor blades.

In these devices there is the danger that on opening the vial s -lintering of the glass takes lace with alf its attendant dangers. According to the present invention this is avoided by combining a striking action with the cutting action, whereby of course a gaging pin mounted on the arm in the direction towards the plate with the incision, :1 spring wire actuated nose connected pivotally to the glass-cutter, of sufiicient length to press the disenga ing pin and thereby the arm and the small p ate on itaway from the glass-cutter when closing the grips of the scissors and to slip from the disengaging pin when the grips of thescissors are closed, whereby the striker is rapidly moved forward in the direction toward the glass-cutter.

In testimony whereof I have hereunto signedmy name. r
